2,2',2''-(2-(5-Iodothiophen-2-yl)ethene-1,1,2-triyl)trithiophene (C18H11IS4) contains sulfur-containing functionality, iodine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
